Post Description

Carbon Copy Cloner backups are better than ordinary backups. Suppose the unthinkable happens while you're under deadline to finish a project — your Mac is unresponsive and all you hear is an ominous, repetitive clicking noise coming from its hard drive. With ordinary backups, you'd spend your day rushing out to a store to buy a new hard drive and then sit in front of your computer reinstalling the operating system and restoring data.

With Carbon Copy Cloner, your data and the operating system's data are all preserved on a bootable volume, ready for production at a moment's notice. When disaster strikes, simply boot from your backup and get back to using your Mac. At your convenience, replace the failed hard drive and then let CCC restore the OS, your data and your settings directly from the backup in one easy step.

Any backup application can save your stuff. A CCC bootable backup will save your productivity too!

Requirements
Intel, Mac OS X 10.6 or later

Version 3.5:
This version of Carbon Copy Cloner requires Mac OS X 10.6 Snow Leopard, OS X 10.7 Lion, or OS X 10.8 Mountain Lion, and is fully qualified on each of those OSes. We will continue to provide user support and bug fixes for Mac OS X 10.4 Tiger and Mac OS X 10.5 Leopard users on CCC 3.4.x for a while longer.
Recovery HD support has been overhauled to better support the concept of "one Recovery HD partition per volume", rather than one per disk. If you have multiple backup volumes with different OSes (e.g. Lion and Mountain Lion), CCC can associate a Recovery HD with each one and apply the appropriate OS to each Recovery HD partition.
We have leveraged code signing within CCC for nearly five years. For GateKeeper compliance on OS X 10.8 Mountain Lion, however, CCC is now signed with an Apple Developer Certificate.
Most of the binaries in the CCC bundle are now 32/64-bit Intel-only binaries.
Fixed an issue that appeared in 10.7.4, specific to Macs running Lion with a 64-bit kernel, in which the /Volumes folder on the destination volume would be locked rather than hidden. This resulted in external volumes being unmountable when booted from the backup volume.
Performance of deleting scheduled tasks is much improved.
CCC previously encountered some performance problems when simultaneously saving very large numbers of scheduled tasks (e.g. > 29). These problems should now be resolved. This is most applicable when updating CCC, or when CCC has been moved and all tasks must be re-saved at the same time.
Updated graphics for High Resolution support on the new MacBook Pro (Retina).
